Finally got a chance to ride today after having my rinehart true duals, pc111 and kn air filter on my bike for over a week. (constantly raining). All I can say is, wow! Sound is incredible and bike runs flawlessley. Don't know why I waited so long to do it. Anybody out there that is thinking about what pipes to get I would recomend the rinehart true duals. The sound is very deep and not to loud at all. You almost feel it more than you here it!
